The Republic of Yemen Navy operates ten Austal 37.5m vessels. The vessels can be deployed for general police missions in coastal waters, customs control and anti-terrorist operations at sea, offshore protection and tracking, surveillance of the exclusive economic zone, defence and protection of national sea areas, and operations within integrated task forces. Austal was selected as the preferred supplier by Republic of Yemen Ministry of Defence in June 2003 to provide a fleet of ten high-speed and reliable patrol boats. The $55m contract included supply of ten patrol vessels, spares, and a substantial training package on vessel operation and maintenance techniques for 60 personnel. Austal was selected after an extensive requirements- and worldwide market-analysis carried out by the international strategic consultancy firm Greenwich House and the Government of Western Australia. The first 37.5m naval patrol boat for the Yemen Navy was launched in February 2004 and the final vessel in December 2004. The first four vessels were delivered in June 2004 and the remaining vessels were delivered through February 2005. The Austal 37.5m patrol vessel is a simplified version of Austal’s 38m Bay Class design. The vessel is easy to maintain and can accommodate 16 crew in two six-berth and two double-berth cabins, and three officers in one single-berth and two double-berth cabins. The overall and waterline lengths of the vessel are 37.5m and 32.4m, respectively. The fast patrol boats have a moulded beam of 7.2m and weight of 90t. The vessel is air-conditioned and consists of commercial-off-the-shelf (COTS) equipment, such as navigation, communication and control systems. The spacious wheelhouse of the vessel with round the horizon-visibility allows seating for up to three persons. The vessel is equipped with two 6.4m rigid-inflatable boats (RIBs) on compensated davits with a 40hp outboard engine. A crane is fitted in the aft on the main deck to allow transfer of general cargo from the vessel to a seaboat or ship to shore. The vessel stores 27,000l of fuel, 10,000l of fresh water, 2,000l of sewage, 500l of sludge, and 500l of lube oil. The vessel incorporates deep V, single chine and semi-displacement monohull design, and is built of aluminium. The hull has a moulded depth of 5m and maximum draft of 2.2m. The Austal 37.5m patrol vessel is equipped with one 25mm twin-barrelled naval gun and two 12.7mm heavy machine guns to execute local and international laws within the territorial waters of Yemen. The machine guns and small arms are fitted with weapons locker. The ready-use ammunition lockers will be placed adjacent to each gun mounting. The Austal 37.5m patrol vessel is powered by two Caterpillar 3512 main engines delivering 1,305kW of power each at 1,800rpm. The twin screw propulsion system also consists of two Reintjes WVS 730 gearboxes, two four-blade fixed pitch propellers, as well as two Perkins Sabre 6TWGM generators, each producing 83kW of power. The patrol boat has a maximum speed of 29kts and cruising speed of 25kts. The patrol range of the vessel is 1,000nm with 20% reserve. The maximum manoeuvrability for the vessels is achieved by twin rudders made of stainless steel. The rudders are offset from the screws to facilitate easy shaft removal. The 30m fast patrol craft are built by Austal for the Trinidad and Tobago Coastguard (TTCG). Multirole vessel (MRV 80) is a long range, high speed patrol ship being developed by Austal. Joint High Speed Vessels (JHSV) are being built by Austal USA as part of the JHSV programme initiated by the US Navy.
